Basswood's Irregular Pentagon and Quadrilateral Pergolas

Here are a couple of interesting pergolas I built during 2013 (a bunch of my woodworking is mega-scale).

One is a pentagon which created some interesting rafter lines. I will dig up a photo of the simple jig used to cut the rafter tails later tonight.

The other is essentially a triangle with a clipped corner. It also has interesting lines. The lattice top is louvered to shade the patio in summer and let sun in during cooler months when the sun is lower in the sky.

Thanks,

Here is another very simple jig, for cutting rafter tails. On irregular shaped projects, I run the rafters, measure and snap chalk lines, trim to length, THEN cut the angled tails.

The jig just clamps in place with a Kreg clamp, then the edge of the circular saw table rides along the jig to get uniform angles and distances. No measuring or marking or following lines. Just set it and cut.

Here is a top view of two of the doubled LVL beams meeting on top of a notched 6×6 post.

And the arsenal of saws used to do the post and beam cutting: Makita 16-5/16" beam saw, Skill worm drive with Prazi beam cutter (chain saw), hand saw, right and left handed 7-1/4" circular saws.

Thanks hobby1 and Loren,

The joinery was quite involved for an outdoor structures.

The light show is pretty cool on both of these, throughout the day and seasons.

Here is a view to the south, on the louvered pergola, showing how much sky you can see that is indicative of how much it lets the sun in during cooler months.

The other shot shows the kind of shading it will yield in the summer.

Fantastic creativity basswood!
I really like the louver effect. Not that difficult but a very dramatic effect. Nice!

Here's a fairly large pergola I did a few years ago. Basic 2×2 lattice on top.
Built on an existing deck that we cleaned and re-stained.
